Abstract
A fast heat rise resistor comprising a substrate, a foil bridge on the surface of the substrate, the foil bridge having an elevated portion and a contact portion, the elevated portion above the substrate, the contact portion in contact with the substrate, a conductive layer attached to the contact portion of said foil bridge. The activation energy and/or response time is reduced as the foil bridge is suspended over the substrate. Another aspect of the invention include a method of manufacturing the foil bridge and application to autoignition vehicle airbags.
